Градиентный бустинг. Реализация с нуля на Python и разбор особенностей его модификаций (XGBoost, CatBoost, LightGBM)

На сегодняшний день градиентный бустинг (gradient boosting machine) является одним из основных production-решений при работе с табличными, неоднородными данными, поскольку обладает высокой производительностью и точностью, а если быть точнее, то его модификации, речь о которых пойдёт чуть позже.

В данной статье представлена не только реализация градиентного бустинга GBM с нуля на Python, но а также довольно подробно описаны ключевые особенности его наиболее популярных модификаций.

Ноутбук с данными алгоритмами можно загрузить на Kaggle (eng) и GitHub (rus).

Gradient Boosting Machine

Gradient Boosting Machine

Как и в случае с Adaboost, градиентный бустинг добавляет базовые модели в ансамбль последовательно, однако вместо обучения моделей с учётом весов на основе ошибок предшественников, в данном случае модели обучаются на остаточных ошибках (residual errors), допущенных предыдущими моделями.

Принцип работы градиентного бустинга для регрессии

Алгоритм строится следующим образом:

1) первоначальному прогнозу присваивается среднее значение y_train для всех образцов;
2) рассчитываются остатки модели на основе антиградиента функции потерь;
3) регрессионное дерево обучается на X_train и остатках, далее делается прогноз на X_train;
4) полученный прогноз добавляется к первоначальному и шаги 2-4 повторяются для каждого дерева;
5) после обучения всех моделей снова создаётся первоначальный прогноз из шага 1;
6) далее делаются прогнозы для X_test на обученных деревьях и добавляются к первоначальному;
7) полученная сумма и будет конечным прогнозом.

Формулы для расчётов

Функция потерь: $L(y_i, F(x_i)) = \frac{1}{2} (y_i - F(x_i))^2$

Остатки: $r_{ik} = -\left[\frac{\partial L(y_i, F(x_i))}{\partial F(x_i)}\right]_ {F(x) = F_{m-1}(x)} = y_{i} - F_{m-1}(x_i)$

Принцип работы градиентного бустинга для классификации

В случае классификации дела обстоят немного сложнее: к каждому уникальному классу необходимо применить one-hot encoding и перевести в вероятности с помощью softmax-функции, а к прогнозам деревьев добавить коэффициент $\gamma$ , который регулирует степень вклада каждого нового дерева в общую модель для снижения переобучения. Также качество прогнозов градиентного бустинга можно существенно улучшить, применив концепцию K-class LogitBoost: для каждого дерева рассчитываются веса, а только потом на их основе остатки.

Алгоритм строится следующим образом:

1) для y_train применяется one-hot encoding и первоначальному прогнозу приcваиваются значения 0 для каждого класса;
2) прогнозы преобразуются в вероятности с помощью softmax-функции;
3) рассчитываются остатки модели на основе антиградиента функции потерь и вероятностей (а также веса в случае LogitBoost);
4) регрессионное дерево обучается на X_train и остатках (а в случае LogitBoost ещё присваиваются веса), далее делается прогноз на X_train;
5) для каждого листа в дереве рассчитываются коэффициенты $\gamma$ на основе остатков, взятых по позициям наблюдений, попавших в определённый в листовой узел;
6) полученные прогнозы для каждого класса и сумма коэффициентов $\gamma$ добавляются к первоначальным;
7) шаги 2-6 повторяются для каждого дерева в каждом классе;
8) после обучения всех моделей создаётся первоначальный прогноз из шага 1;
9) далее делаются прогнозы для X_test на обученных деревьях по каждому классу и добавляются к первоначальным;
10) классы с максимальной суммой и будут конечным прогнозом.

Формулы для расчётов

Функция потерь:

$L(\{y_k, F_k(x)\}_{1}^{K}) = -\sum\limits_{k=1}^{K} y_k \ log \ p_k(x)$

Вероятность каждого класса:

$p_k(x) = softmax(F_k(x)) = \frac{e^{F_k(x)}}{\sum\limits_{l=1}^{K} e^{F_l(x)}}$

Остатки:

$r_{ik} = -\left[\frac{\partial L(\{y_{il}, F_l(x_i)\}_{l=1}^{K})}{\partial F_k(x_i)}\right]_ {\{F_l(x) = F_{l,m-1}(x)\}_{1}^{K}} = y_{ik} - p_{k,m-1}(x_i)$

Коэффициент $\gamma$ :

$\gamma_{jkm} = \frac{K-1}{K} \frac{\sum_{x_i \in R_{jkm}} r_{ik}} {\sum_{x_i \in R_{jkm}} |r_{ik}| (1 - |r_{ik}|)}$

Веса для K-class LogitBoost:

Остатки для K-class LogitBoost:

$r_{ik} = \frac{K-1}{K} \frac{y_{ik} - p_k(x_i)}{w_k(x_i)}$

Обучение моделей и оценка полученных результатов

В случае классификации ручная реализация немного отличается в плане точности от scikit-learn — это связано с тем, что в последней применяется более усложнённый подход для прогнозирования и расчёта остатков, но суть остаётся прежней, и в большинстве случаев работает примерно также как и ручная реализация, особенно в сравнении с LogitBoost модификацией.

В случае регрессии, ошибка в ручной реализации даже немного ниже, чем в scikit-learn — различия незначительны.

Также стоит отметить, что в scikit-learn есть особая версия градиентного бустинга — HistGradientBoosting на основе LightGBM, предназначенная для работы с большими наборами данных, которая отрабатывает гораздо быстрее и чаще лучше, чем классический градиентный бустинг.

Полученные результаты приведены ниже.

Преимущества и недостатки градиентного бустинга (GBM)

Преимущества:

высокая точность;
хорошо работает с неоднородными данными;
лежит в основе других модификаций градиентного бустинга.

Недостатки:

низкая скорость обучения при работе с большими датасетами;
отсутствие возможности работы с категориальными признаками;
возможность переобучения из-за плохой предобработки данных.

Стоит отметить, что вышеперечисленные недостатки были устранены частично либо полностью в модификациях градиентного бустинга, про которые сейчас и пойдёт речь.

Особенности XGBoost

XGBoost (Extreme Gradient Boosting) является, пожалуй, самой популярной модификацией градиентного бустинга на сегодняшний день, с помощью которой было выиграно множество соревнований на Kaggle. Рассмотрим причины по которым так произошло.

В отличие от GBM в XGboost изначальный прогноз регрессионного дерева устанавливается f_0 (x) = 0.5 и вместо пней с глубиной 3 берутся более глубокие деревья с листьями в диапазоне от 8 до 32 как в случае регрессии, так и классификации, а к функции потерь добавляется регуляризация (L1 или L2 на выбор), которая штрафует дерево с высокой суммой нормы значений в листьях. Данная сумма представлена в виде целевой функции, расчёт значений которой аппроксимируется разложением в ряд Тейлора 2-го порядка.

Формулы для расчётов

Целевая функция:

$Obj^{\ t} = \sum\limits_{i=1}^{N} L(y_i, \hat{y_i}^{(t-1)} + f_t(x_i)) + \Omega(f_t)$

L2-регуляризация:

$\Omega(f_t) = \gamma \ T + \frac{1}{2} \lambda||w||^2$

Аппроксимация целевой функции разложением в ряд Тейлора 2-го порядка:

$Obj^{\ t} \approx \sum\limits_{i=1}^{N} [L(y_i, \hat{y_i}^{(t-1)}) + g_i f_t(x_i) + \frac{1}{2} h_i f_t^2(x_i) ] + \gamma \ T + \frac{1}{2} \lambda \sum\limits_{j=1}^{T} w_j^2 = \\ = \sum\limits_{j=1}^{T} [(\sum\limits_{i \in I_j}g_i) w_j + \frac{1}{2} (\sum\limits_{i \in I_j}h_i + \lambda) w_j^2 ] + \gamma \ T$

Где:

градиент первого порядка: ;
градиент второго порядка (гессиан): ;
параметры регуляризации: $\gamma, \lambda$ .

Приближение второго порядка удобно с вычислительной точки зрения, поскольку большинство членов одинаковы на каждой отдельной итерации и большая часть выражения может быть вычислена один раз и повторно использована как константа для всех остальных разбиений, и в таком случае единственное, что остаётся вычислить — это f_t(x_i) и $\Omega(f_t)$ .

Оптимальное значение веса j-го листового узла в дереве рассчитывается следующим образом:

$w^*_j = -\frac{\sum_{i \in I_j} g_i}{\sum_{i \in I_j} h_i + \lambda}$

Мера загрязнённости представляет из себя качество структуры дерева q и рассчитывается следующим образом:

$Obj^{\ t} = -\frac{1}{2} \sum\limits_{j=1}^{T} \frac{(\sum_{i \in I_j} g_i)^2}{\sum_{i \in I_j} h_i + \lambda} + \gamma \ T$

Чем меньше это значение, тем лучше структура дерева.

Поскольку перечисление всевозможных древовидных структур и выбор наилучшей весьма осложнён, мы можем оптимизировать данную задачу, добавляя по одному разбиению узла дерева за раз. В частности, мы итеративно добавляем ветви к дереву, используя жадный алгоритм, а информационный прирост будет выглядеть следующим образом:

$gain = \frac{1}{2} \left[\frac{(\sum_{i \in I_L} g_i)^2}{\sum_{i \in I_L} h_i + \lambda} + \frac{(\sum_{i \in I_R} g_i)^2}{\sum_{i \in I_R} h_i + \lambda} - \frac{(\sum_{i \in I} g_i)^2}{\sum_{i \in I} h_i + \lambda} \right] - \gamma$

Информационный прирост будет показывать изменение чистоты узла после его разбиения. Его максимальное значение будет соответствовать наилучшему пороговому значению (критерию разбиения) узла в дереве.

Стоит также упомянуть, что в XGBoost поддерживается выбор линейных моделей в качестве базовых, но, в целом, они работают хуже деревьев.

Дополнительные оптимизации в XGBoost

Weighted quantile sketch

В случае работы с большими наборами данных в XGBoost используется приближённый жадный алгоритм. Это означает, что вместо тестирования всех возможных пороговых значений мы тестируем только квантили. Используя распараллеливание для разделения набора данных и создания ветвей в каждом дереве независимо друг от друга чтобы несколько ядер могли работать с ними одновременно, алгоритм взвешенных квантилей (weighted quantile sketch) объединяет данные в приближённую гистограмму, разделённую на взвешенные квантили, которые помещают наблюдения с прогнозами низкой достоверности в квантили с меньшим количеством наблюдений.

Cache-aware access & out-of-core computing

Для более быстрого вычисления прогнозов градиенты и гессианы хранятся в кэш-памяти (cache-aware access), а в случае с датасетами большого размера, когда недостаточно кэш и оперативной памяти, задействуется память из жёсткого диска. Учитывая, что чтение данных на жёстком диске выполняется гораздо медленнее чем в кэш-памяти, для ускоренной обработки производится их компрессия. Данные хранятся в единицах памяти, называемых блоками, информация в которых хранится в формате сжатых столбцов, отсортированных по соответствующим значениям параллельно с использованием всех доступных ядер ЦП, а распаковка каждого блока осуществляется в независимом потоке при загрузке в память. Данная техника называется "вычисление вне ядра" (out-of-core computing). При наличии нескольких жёстких дисков, применяется параллельное сегментирование блоков для каждого жёсткого диска (sharding).

При использовании сжатых данных необходимо учитывать, что процесс сжатия и распаковки занимает дополнительное время, поэтому выбор алгоритма сжатия (с потерями и без) и его параметров может повлиять на производительность в целом, однако это всё равно значительно быстрее чтения без сжатия.

Sparsity-aware split finding

В XGboost также поддерживается работа с пропусками. Суть заключается в следующем: из исходного датасета убираются наблюдения с пропусками и представляются как отдельный датасет. После построения дерева для наблюдений без пропусков рассчитываются их остатки, далее — остатки для наблюдений с пропусками, которые присоединяются к остаткам дерева как для левого, так и для правого узла. В конце рассчитывается информационный прирост (gain) для каждого узла в дереве: выбирается порог для разбиения с максимальным приростом. Данная техника называется "поиск разбиения с учётом разряженности" (sparsity-aware split finding).

Обучение на GPU

Для ускорения процесса обучения в XGBoost реализована поддержка GPU с помощью параметров device="cuda" и tree_method="gpu_hist". Также стоит отметить, что в данном алгоритме поддерживается полностью распределённое обучение на GPU с использованием Dask, Spark и PySpark.

Пакетная реализация XGBoost и оценка полученных результатов

Благодаря вышеуказанным оптимизациям и особенностям XGBoost работает лучше классической реализации, что видно на примере классификации, однако на примере регрессии в данном случае результат оказался хуже. Если хорошо подготовить данные и поэкспериментировать с настройкой гиперпараметров, XGBoost будет работать гораздо лучше как в случае регрессии, так и классификации.

Особенности CatBoost

CatBoost (Categorical Boosting) — более эффективная реализация градиентного бустинга от компании Яндекс, особенностью которой является возможность работы с категориальными признаками без их предварительной обработки. Разберёмся подробнее как это происходит.

Ordered target (CatBoost) encoding

При кодировании категориальных признаков к бустингам применяется один из нескольких классических подходов:

target encoding;
one-hot encoding (хорошо работает лишь в том случае, когда в признаках содержится небольшое количество значений);
feature hashing в несколько корзин (исходные данные преобразуются в уникальную последовательность символов (хэш-значения), которые разбиваются на группы (корзины) и обрабатываются параллельно с последующим применением target или one-hot encoding);
mean target encoding (рассчитывается новое значение для текущего категориального признака как среднее значение целевой переменной по датасету);
leave-one-out (рассчитывается среднее значение целевой переменной по всем объектам кроме текущего);
leave-bucket-out (рассчитывается среднее значение целевой переменной на одной части данных и применяется для оставшихся других);

Однако все вышеперечисленные способы так или иначе приводят к утечке данных и переобучению, и данную проблему можно частично решить с применением mean target encoding на отложенной выборке, что работает заметно лучше, но такой способ не идеален так как остаётся меньше данных для обучения и вычисления статистик по категориальным признакам.

В CatBoost применяется модифицированный подход к mean target encoding, называемый Ordered target (CatBoost) encoding, который состоит из 3-х нижеперечисленных этапов.

Случайная перестановка

Образцы в наборе данных перемешиваются случайным образом, что позволяет создать более сбалансированный набор данных и снизить переобучение.

Статистики «по прошлому»

После случайной перестановки рассчитывается новое значение для текущего категориального признака следующим образом:

$CTR = \frac{TargetSum + Prior}{TotalCount + 1}$

Prior — константа, определяемая как среднее арифметическое целевых значений.

TargetSum — сумма целевых значений для конкретного категориального признака до текущего момента.

TotalCount — количество всех наблюдений для конкретного категориального признака до текущего момента.

Данная формула может быть применима как для регрессии, так и для мультиклассификации.

Пошаговый пример с нуля для мультиклассификации

!pip install category_encoders

from category_encoders.cat_boost import CatBoostEncoder

train = pd.DataFrame({"color": ["red", "blue", "black", "black", "blue", "blue", "red", "blue"]})
target = pd.Series([2, 1, 2, 1, 0, 3, 0, 1])

cbe_encoder = CatBoostEncoder()
train_cbe = cbe_encoder.fit_transform(train, target)
prior = target.mean()

print(f'prior: {prior}', '', sep='\n')
print(train_cbe)


prior: 1.25

    color
0  1.2500
1  1.2500
2  1.2500
3  1.6250
4  1.1250
5  0.7500
6  1.6250
7  1.3125

В случае c числовыми признаками создаётся набор меток с помощью квантования и производится их бинаризация на k классов: все значения до границы (метки) относятся к классу 0, а после к классу 1. Далее процедура схожа со случаем выше.

В CatBoost поддерживаются следующие виды квантования:

мода;
медианная сетка;
равномерная сетка + квантили (размер квантования уменьшается вдвое и разбиения (пороговые значения) объединяются по одному из двух способов: медиана или равномерная сетка);
MaxLogSum — максимизируется значение следующего выражения внутри каждого сегмента:

$\sum\limits_{i=1}^{n} log \ w_i$

MinEntropy — минимизируется значение следующего выражения внутри каждого сегмента:

$\sum\limits_{i=1}^{n} w_i \ log \ w_i$

GreedyLogSum — максимизируется аппроксимация жадным способом следующего выражения внутри каждого сегмента:

$\sum\limits_{i=1}^{n} log \ w_i$

где n — число различных объектов в сегменте, w (weight) — число повторений объекта в сегменте.

Комбинация категориальных признаков

В CatBoost используется комбинация категориальных признаков (например, красный диван, синий диван, синий стул и так далее), что позволяет модели учитывать неочевидные взаимосвязи между ними и улучшить качество итоговых прогнозов в целом. Для избегания экспоненциального роста комбинаций категориальных признаков, их создание происходит не перед началом обучения, а в момент построения каждого дерева жадным алгоритмом отдельно.

Структура решающих деревьев и упорядоченный бустинг

В качестве базовых моделей в CatBoost используются симметричные односторонние деревья, имеющие одинаковую глубину и ширину. Создатели алгоритма считают, что такой подход позволяет ускорить обучение и создавать деревья, которые менее подвержены переобучению.

Для нахождения наилучшего критерия разбиения в узле используется косинусное сходство — его максимальное значение будет соответствовать лучшему критерию:

$Cosine \ Similarity = \frac{ \sum\limits_{i=1}^{n} A_i B_i}{\sqrt{\sum\limits_{i=1}^{n} A_i^2} \sqrt{\sum\limits_{i=1}^{n} B_i^2}}$

где A — вектор с остаточными ошибками, B — вектор с прогнозами в листовых узлах.

Проблема классического бустинга заключается в том, что прогнозы базовых моделей могут иметь высокое смещение, что в конечном счёте приводит к переобучению модели в целом — это обусловлено тем, что обучение и оценка деревьев производится на одинаковом наборе данных (X_train). Данная проблема решается с помощью метода линейной аппроксимации упорядоченного бустинга (Ordered Boosting), суть которого заключается в следующем: данные перемешиваются случайным образом и после чего текущее дерево обучается на m-1 образцах с учётом остатков предыдущего, что очень похоже на принцип в ordered target encoding, то есть изначально берётся один образец из набора данных и модель учится на всех образцах до него, то есть на нулях, далее берётся два образца и модель учится на одном, после чего рассчитываются остатки, которые будут использованы для следующей модели и так далее. Такой подход позволяет произвести обучение дерева со сложностью O(log(m)) вместо O(m^2) .

Структура симметричного одностороннего дерева

Дополнительные возможности CatBoost

Работа с пропусками

Поддерживаются следующие режимы обработки пропусков:

"Forbidden" — пропуски интерпретируются как ошибки.
"Min" — пропуски обрабатываются как минимальное значение (меньшее, чем все остальные значения) для объекта.
"Max" — пропуски обрабатываются как максимальное значение (превышающее все остальные значения) для объекта.

Режим обработки по умолчанию — Min. Также при выборе деревьев учитывается разбиение, отделяющее пропущенные значения от всех остальных.

Snapshots

Данный параметр (save_snapshot=True) позволяет создавать резервные копии промежуточных результатов. Если происходит неожиданное прерывание обучения (например, случайное выключение компьютера), то оно может быть продолжено из сохранённого состояния и в таком случае не нужно повторять завершённые итерации построения деревьев.

Обучение на GPU

В CatBoost возможно обучение не только на нескольких GPU, но и сразу на нескольких серверах с GPU, что фактически позволяет запустить распределённое обучение и использовать датасеты любого размера. Данная процедура позволяет значительно ускорить работу алгоритма: чем больше датасет, тем больше будет прирост в производительности в сравнении с обучением на CPU. Для того чтобы этим воспользоваться достаточно указать task_type="GPU".

Пакетная реализация CatBoost и оценка полученных результатов

Как можно заметить из примера классификации, не смотря на большое количество улучшений, CatBoost далеко не всегда показывает высокие результаты в сравнении с другими реализациями градиентного бустинга, как это заявляют его разработчики, особенно заметна разница в случае с несбалансированными наборами данных. Однако, стоит отметить, что в случае хорошей подготовки данных, при прочих равных, в ряде случаев CatBoost будет отличаться от других модификаций немного более высокой точностью.

В случае регрессии, когда нет явно выраженной проблемы как в случае выше, CatBoost справляется довольно хорошо.

Особенности LightGBM

LightGBM (Light Gradient Boosting Machine) — реализация градиентного бустинга от компании Microsoft, способная обрабатывать большие наборы данных и при этом обеспечивать высокую точность. Рассмотрим более подробно ключевые особенности, которые на это повлияли.

Gradient-based One-Side Sampling (GOSS)

В отличие от классического градиентного бустинга, где регрессионные деревья обучаются на всём множестве X_train, в LightGBM деревья обучаются на подмножестве данных, полученном с помощью одностороннего отбора на основе градиента (GOSS), суть которого заключается в сортировке и выборе образцов top N с наибольшим градиентом — это означает, что именно этим данным следует уделить особое внимание, поскольку на них дерево будет ошибаться больше всего. Помимо этого, случайным образом производится отбор части образцов с низким градиентом с последующим присвоением им весов $\frac{1-a}{b}$ , чтобы избежать изменений в распределении данных. В данном случае — доля образцов top N в процентах с наибольшим градиентом, — доля образцов в процентах с низким градиентом.

Проще говоря, использование GOSS позволяет значительно ускорить обучение каждого последующего дерева в ансамбле путём уменьшения обучающего набора данных без особой потери в качестве прогнозов в большинстве случаев.

Histogram-based tree node splitting

При поиске наилучшего критерия разбиения узла в LightGBM также можно использовать гистограмму значений признаков: перебираются все пороговые значения гистограммы вместо всех значений признаков, что позволяет существенно ускорить поиск наилучшего критерия. Например, для признака "рост" можно использовать вопросы "рост" ⩽ 160, "рост" ⩽ 170 вместо "рост" ⩽ 163, "рост" ⩽ 167 и так далее. Как можно было заметить, гистограммы применяются в том или ином виде во всех трёх модификациях градиентного бустинга.

Exclusive Feature Bundling (EFB)

Предположим, что тем или иным образом в датасете имеются закодированные категориальные признаки, большинство из которых являются взаимоисключающими (те, которые одновременно не принимают ненулевые значения). При большом числе таких признаков обучение модели может занять слишком много времени и для решения данной проблемы в LightGBM применяется понижение размерности пространства признаков путём объединения взаимоисключающих признаков (EFB).

Стоит отметить, что в действительности строго взаимоисключающие признаки в данных встречаются крайне редко. Поэтому вводится такое понятие как доля конфликтов между признаками — отношение наблюдений от общего числа, где два признака принимают одновременно ненулевые значения.

Допустим, имеется датасет с признаками F0−F4 . В первую очередь стоит установить допустимую долю конфликтов, например, 25%. Тогда в случае из 8 образцов допустимое число конфликтов будет составлять 2. Далее строится матрица конфликтов между всеми признаками и производится подсчёт общей суммы конфликтов для каждого признака, после чего происходит их сортировка в порядке убывания.

На основе матрицы конфликтов строится взвешенный граф, у которого в полученном порядке отсекаются все рёбра с числом конфликтов, превышающим допустимое значение.

Работа Exclusive Feature Bundling с нуля на простом примере

Первой связкой будет F_0−F_1 . Не смотря на то что F_1−F_2 и F_1−F_3 не конфликтуют, их объединение невозможно из-за конфликтов F_0−F_2 и F_0−F_3 . Следующей связкой будет F_2−F_4 . Не смотря на то, что F_4 и F_3 не конфликтуют, их объединение невозможно из-за конфликта F_2−F_3 . Последним остаётся признак F_3 .

Новая связка будет состоять из ненулевых значений первого признака и ненулевых значений второго плюс смещение, равное максимальному значению первого признака: смещение каждого следующего признака будет равно сумме максимальных значений предыдущих. В случаях, когда наблюдается конфликт, берётся значение последнего признака со смещением.

Подробные расчёты приведены ниже.

Нетрудно заметить, что алгоритм EFB можно оптимизировать, игнорируя вычисления для всех нулевых значений в признаках. Также данную оптимизацию можно применить к histogram-based tree node splitting, что в целом снизит сложность построения гистограммы с O(data) до O(non-zero data).

Leaf-wise tree growth

Вместо построения деревьев слой за слоем, в LightGBM деревья строятся в глубину: рост продолжается в листовом узле с наибольшим информационным приростом, в результате чего дерево получается глубоким и несимметричным. Чаще всего такой подход превосходит симметричные деревья в плане точности.

Обучение на GPU

При работе с большими датасетами в LightGBM поддерживается обучение не только на GPU, но и распределённое обучение сразу на нескольких машинах.

На данный момент существуют следующие подходы:

Data parallel (образцы датасета разбиваются на локальные гистограммы, каждая из которых обрабатывается отдельно);
Feature parallel (признаки датасета разбиваются на локальные гистограммы, каждая из которых обрабатывается отдельно);
Voting parallel (на каждом процессе локально выбирается K лучших признаков для разбиения, после чего выбирается наилучший из них глобально).

Пакетная реализация LightGBM и оценка полученных результатов

Как можно заметить, в случае классификации LightGBM показал результат из коробки значительно лучше, чем предыдущие модификации бустинга. Также стоит отметить, что из всех трёх рассмотренных модификацией градиентного бустинга LightGBM является самой быстрой: чем больше датасет, тем сильнее будет заметна разница в плане скорости.

Какой бустинг лучше

Однозначного ответа на вопрос какой бустинг лучше нет. Если раньше можно было сказать, что при работе с категориальными признаками лучше использовать CatBoost, когда важна скорость — LightGBM, ну или XGBoost, если хочется стабильное решение и нет времени на эксперименты, то сейчас такое утверждение будет неверным: как можно было заметить, все три модификации успели скопировать друг у друга много хороших идей, но исторически они отличались довольно сильно.

Более правильным будет утверждение, что выбор наилучшего бустинга будет зависеть от конкретной задачи и данных, которые применяются для обучения модели: в разных сценариях одни и те же алгоритмы могут показывать как лучшие результаты в плане скорости и точности, так и наоборот — худшие. Таким образом, выбор наиболее оптимального бустинга будет заключаться в проведении экспериментов с разными модификациями и сравнении полученных результатов.

Несколько полезных источников со сравнением бустингов: один, два, три.

I never imagined I’d fall for a crypto romance scam but it happened. Over the course of a few months, I sent nearly $150,000 worth of Bitcoin to someone I genuinely believed I was building a future with. When they disappeared without a trace, I was left heartbroken, humiliated, and financially devastated. For a long time, I didn’t tell anyone. I felt ashamed. But eventually, while searching for answers, I came across a Reddit thread that mentioned Agent Jasmine Lopez. I reached out, not expecting much. To my surprise, she treated me with kindness, not judgment. She used advanced tools like blockchain forensics, IP tracing, and smart contract analysis and with persistence and legal support, she was able to recover nearly 85% of what I lost. I know not everyone gets that kind of outcome, but thanks to [email protected] WhatsApp at +44 736-644-5035, I’ve started to reclaim not just my assets, but my confidence and peace of mind. If you’re going through something similar, you’re not alone and there is hope.

A few months ago, I fell for what looked like a legitimate online trading platform. The website was sleek, the support team was responsive, and they even showed me fake profit charts that seemed to grow daily. I started small, and after a few test withdrawals worked, I invested more eventually depositing 2 Bitcoin in hopes of long-term returns. But one morning, when I tried to withdraw, everything changed. The platform suddenly locked my account, claiming there were additional fees to release my funds. The support chat stopped responding, and the website started giving error messages. That’s when I realized I’d been scammed. I was devastated. Two Bitcoins wasn’t pocket change, it was my savings. I filed reports online, but everyone told me it was impossible to recover crypto once it’s sent. Then, through a discussion forum, I came across Dexdert Net Recovery, a team specializing in tracing and recovering stolen digital assets. Skeptical but desperate, I reached out. Their response was immediate and professional. They asked for transaction IDs, wallet addresses, screenshots of my correspondence with the fake platform, and any proof of payment I had. Within days, their analysts traced the stolen Bitcoin through multiple wallets using blockchain forensics, They updated me step-by-step, Working with their recovery experts and blockchain partners, Dexdert Net Recovery successfully froze the funds and verified ownership of my wallet. After 2 days of persistence and verification, I finally saw my 2 Bitcoin restored back into my own wallet. I couldn’t believe it. What stood out most wasn’t just that they recovered my funds, but how transparent and supportive the Dexdert team was throughout the process. They educated me on crypto safety, how to spot fake trading sites, and how to secure my digital assets in the future. Dexdert Net Recovery truly lives up to its name.

When my USD was stolen, for anyone who has fallen victim to one of the bitcoin binary investment scams that are currently ongoing, I felt betrayal and upset. But then I was reading a post on site when I saw a testimony of Wendy Taylor online who recommended that Capital Crypto Recovery has helped her recover scammed funds within 24 hours. after reaching out to this cyber security firm that was able to help me recover my stolen digital assets and bitcoin. I’m genuinely blown away by their amazing service and professionalism. I never imagined I’d be able to get my money back until I complained to Capital Crypto Recovery Services about my difficulties and gave all of the necessary paperwork. I was astounded that it took them 12 hours to reclaim my stolen money back. Without a doubt, my USDT assets were successfully recovered from the scam platform, Thank you so much Sir, I strongly recommend Capital Crypto Recover for any of your bitcoin recovery, digital funds recovery, hacking, and cybersecurity concerns.

I met an individual on an international dating app, Bumpy. After talking for a few months, the individual encouraged me to start investing on crypto asset trading platform, btc01.org. I started trading and believed I was making profit until I tried to withdraw some of my money, I was asked to pay extra for tax which I did and they kept asking then I knew I have been scammed, I had to contact HACKWEST AT WRITEME DOT COM who then helped to recover the money, the total money I invest is $198,000 in bitcoin. The website is no longer operational. If anyone is in a similar issue, you can as well contact HACK WEST. They also fixed my credit report.

CRYPTO SCAM RECOVERY SUCCESSFUL – A TESTIMONIAL OF LOST PASSWORD TO YOUR DIGITAL WALLET BACK. My name is Robert Alfred, Am from Australia. I’m sharing my experience in the hope that it helps others who have been victims of crypto scams. A few months ago, I fell victim to a fraudulent crypto investment scheme linked to a broker company. I had invested heavily during a time when Bitcoin prices were rising, thinking it was a good opportunity. Unfortunately, I was scammed out of $120,000 AUD and the broker denied me access to my digital wallet and assets. It was a devastating experience that caused many sleepless nights. Crypto scams are increasingly common and often involve fake trading platforms, phishing attacks, and misleading investment opportunities. In my desperation, a friend from the crypto community recommended Capital Crypto Recovery Service, known for helping victims recover lost or stolen funds. After doing some research and reading multiple positive reviews, I reached out to Capital Crypto Recovery. I provided all the necessary information—wallet addresses, transaction history, and communication logs. Their expert team responded immediately and began investigating. Using advanced blockchain tracking techniques, they were able to trace the stolen Dogecoin, identify the scammer’s wallet, and coordinate with relevant authorities to freeze the funds before they could be moved. Incredibly, within 24 hours, Capital Crypto Recovery successfully recovered the majority of my stolen crypto assets. I was beyond relieved and truly grateful. Their professionalism, transparency, and constant communication throughout the process gave me hope during a very difficult time.

I never imagined I’d fall for a crypto romance scam but it happened. Over the course of a few months, I sent nearly $184,000 worth of Bitcoin to someone I genuinely believed I was building a future with. When they disappeared without a trace, I was left heartbroken, humiliated, and financially devastated. For a long time, I didn’t tell anyone. I felt ashamed. But eventually, while searching for answers, I came across a Reddit thread that mentioned Agent Jasmine Lopez a crypto recovery agent. I reached out, not expecting much. To my surprise, she treated me with kindness, not judgment. She used advanced tools like blockchain forensics, IP tracing, and smart contract analysis and with persistence and legal support, she was able to recover nearly 85% of what I lost. I know not everyone gets that kind of outcome, but thanks to [email protected] WhatsApp at +44 736-644-5035, I’ve started to reclaim not just my assets, but my confidence and peace of mind. If you’re going through something similar, you’re not alone and there is hope.

I lost $52,000 in USDT to a scam. That hit me hard. USDT is a stable cryptocurrency tied to the US dollar. It keeps its value steady. I thought I had found a sure way to grow my money. Things looked good at first. I even built up profits to $120,000. But when I went to pull out my earnings, the platform blocked me. No access. No funds. Panic set in. I felt trapped and helpless. Scams like this target crypto users all the time. They promise quick gains. Then they vanish with your money. Each year, people lose billions to these tricks. I searched for help everywhere. Forums, support groups. Nothing worked. That's when a friend stepped in. He had faced a similar mess before. He told me about Sylvester Bryant. My friend swore by his skills. So I reached out right away. His email is [email protected]. Sylvester Bryant turned it all around. He listened to my story without judgment. His team got to work fast. They started by reviewing every detail of the scam. Step by step, they traced the path of my stolen USDT. They used tools to follow the blockchain. That's the public record of crypto transactions. It shows where funds move. But scammers hide their tracks. Bryant's group dug deep. They contacted exchanges and networks involved. Day after day, they pushed forward. No shortcuts. They kept me updated the whole time. Every email, every call was clear and honest. In the end, they recovered my full amount. That $52,000 came back to me. The process took focus and grit. Bryant's honesty stood out. He charged no hidden fees. Just straight work for results. My stress melted away. I could breathe again. Sleep came easier. My trust in recovery options grew. If a scam has taken your money, act now. Reach out to Sylvester Bryant. He handles cases like this with care. Email him at [email protected]. Or on WhatsApp at +1 512 577 7957 or +44 7428 662701. Don't wait. Get your funds back.

She used advanced tools like blockchain forensics, IP tracing, and smart contract analysis and with persistence and legal support, she was able to recover nearly 85% of what I lost. I know not everyone gets that kind of outcome, but thanks to [email protected] WhatsApp at +44 736-644-5035, I’ve started to reclaim not just my assets, but my confidence and peace of mind.

Legitimate crypto recovery companies in Australia - HIRE TREQORA INTEL Sometimes, life can be unpredictable and present us with unexpected twists and turns. On October 15, 2025, I had an experience that taught me a valuable lesson about the importance of vigilance and caution in the digital age. It began when I met someone on TikTok who claimed to have a surefire way to generate significant profits from Ethereum investments. The individual, who went by the name of Mr. Oscar, presented himself as a financial expert with a proven track record of success. Intrigued by the promise of easy money, I decided to invest a substantial amount of my savings into the Ethereum venture. However, I soon discovered that I had fallen victim to a sophisticated scam. Mr. Oscar had fake credentials and a history of deceiving numerous people, leaving them financially devastated and feeling betrayed, I thought I had lost my investment forever. But I was determined to recover my stolen Ethereum and sought help from a reputable firm specializing in cybersecurity. That's when I stumbled upon Treqora Intel, a company with a stellar reputation for assisting victims of online scams. With the support of Treqora Intel , I was able to recover my lost funds in a remarkably short period. Their team of experts was efficient, responsive, and empathetic, making the recovery process as smooth as possible. I was impressed by their professionalism and commitment to helping individuals like me who have been affected by online scams. This experience has taught me to be more cautious when interacting with strangers online, especially when it comes to investment opportunities that seem too good to be true. It has also reminded me of the importance of verifying the credibility of individuals and companies before making any financial decisions. I am grateful to TREQORA INTEL for their assistance and hope that my story can serve as a warning to others to be vigilant in the online world. By being aware of the potential risks and taking necessary precautions, we can protect ourselves from falling prey to scams and ensure a safer online experience.Email:support@treqora. com Whats_App: ‪‪‪‪‪‪‪+1 (7 7 3 ) 9 7 7 - 7 8 7 7‬‬‬ ‬‬ ‬‬, Website: Treqora. com.

I never imagined I’d fall for a crypto romance scam but it happened. Over the course of a few months, I sent nearly $184,000 worth of Bitcoin to someone I genuinely believed I was building a future with. When they disappeared without a trace, I was left heartbroken, humiliated, and financially devastated. For a long time, I didn’t tell anyone. I felt ashamed. But eventually, while searching for answers, I came across a Reddit thread that mentioned Agent Jasmine Lopez a crypto recovery agent. I reached out, not expecting much. To my surprise, she treated me with kindness, not judgment.

A scam cost me $72,000 in USDT. It shook me up. USDT is a stablecoin linked to the dollar. Its value stays even. I believed I found a safe path to build my wealth. At the start, all seemed fine. My account grew to $120,000 in profits. But when I tried to withdraw, the site locked me out. No way to get in. No money left. Fear took over. I felt stuck and alone. These frauds hit crypto investors often. They lure with fast riches. Then they steal your cash and disappear. Billions vanish each year from such schemes. I looked for aid in every spot. Online boards. Help chats. None helped. Then a buddy offered support. He had dealt with the same issue once. He mentioned Sylvester Bryant. My friend praised his expertise. I contacted him at once. His email is [email protected]. Sylvester Bryant changed everything. He heard my tale with no blame. His crew jumped in quickly. They checked all scam details first. One by one, they followed my lost USDT trail. They used software to track the blockchain. That is the open log of coin transfers. It reveals fund paths. Scammers try to cover their steps. Bryant's team went far. They reached out to related platforms and services. Each day brought progress. No easy ways. They shared updates with me always. Each message and talk stayed open and true. Finally, they got back every dollar. My $52,000 returned whole. The effort needed drive and resolve. Bryant's fairness shone through. He added no secret costs. Only fair pay for the job. My worry faded. I relaxed once more. Nights grew calm. My faith in recovery grew strong. If fraud stole your funds, move fast. Contact Sylvester Bryant. He treats such cases with skill.

God bless Capital Crypto Recover Services for the marvelous work you did in my life, I have learned the hard way that even the most sensible investors can fall victim to scams. When my USD was stolen, for anyone who has fallen victim to one of the bitcoin binary investment scams that are currently ongoing, I felt betrayal and upset. But then I was reading a post on site when I saw a testimony of Wendy Taylor online who recommended that Capital Crypto Recovery has helped her recover scammed funds within 24 hours. after reaching out to this cyber security firm that was able to help me recover my stolen digital assets and bitcoin. I’m genuinely blown away by their amazing service and professionalism. I never imagined I’d be able to get my money back until I complained to Capital Crypto Recovery Services about my difficulties and gave all of the necessary paperwork. I was astounded that it took them 12 hours to reclaim my stolen money back.

Recover All Lost Cryptocurrency From Scammers TREQORA INTEL has exhibited unparalleled strength in the realm of recovery. They stand out as the premier team to collaborate with if you encounter withdrawal difficulties from the platform where you’ve invested. Recently, I engaged with them to recover over a million dollars trapped in an investment platform I’d been involved with for months. I furnished their team with every detail of the investment via Email (SUPPORT @ TREQORA . C O M”), including accounts, names, and wallet addresses to which I sent the funds. This decision proved to be the best I’ve made, especially after realizing I had been sc**med by the company. Initially, I harbored doubts about their services, but I was proven wrong. TREQORA INTEL ensures exemplary service delivery and ensures the perpetrators face justice. They employ advanced techniques to ensure you regain access to your funds. Understandably, many individuals who have fallen victim to investment scams may still harbor trepidation about engaging in online services again due to the trauma of being sc**med. However, I implore you to take action. Seek assistance from TREQORA INTEL today and witness their remarkable capabilities firsthand. Among the myriad of hackers available, TREQORA INTEL stands head and shoulders above the rest. While I may not have sampled all of them, the few I attempted to work with previously were unhelpful and solely focused on depleting the little funds I had left. I am grateful that I resisted their enticements, and despite the time it took me to discover TREQORA INTEL, they ultimately fulfilled my primary objective. I am confident they will execute the task proficiently. Without their intervention, I would have remained despondent and perplexed indefinitely.

I have invested in crypto trading platforms for about 10yrs thinking I was ensuring myself a retirement income, only to find that all my assets were either frozen, I believed my assets were secure — until I discovered that my BTC funds had been frozen and withdrawals were impossible. It was a devastating moment when I realized I had been scammed, and I thought my Bitcoin was gone forever, Everything changed when a close friend recommended the Capital Crypto Recover Service. Their professionalism, expertise, and dedication enabled me to recover my lost Bitcoin funds back — more than €560.000 DEM to my BTC wallet. What once felt impossible became a reality thanks to their support. If you have lost Bitcoin through scams, hacking, failed withdrawals, or similar challenges, don’t lose hope.

A scam cost me $72,000 in USDT. It shook me up. USDT is a stablecoin linked to the dollar. Its value stays even. I believed I found a safe path to build my wealth. At the start, all seemed fine. My account grew to $120,000 in profits. But when I tried to withdraw, the site locked me out. No way to get in. No money left. Fear took over. I felt stuck and alone. These frauds hit crypto investors often. They lure with fast riches. Then they steal your cash and disappear. Billions vanish each year from such schemes. I looked for aid in every spot. Online boards. Help chats. None helped. Then a buddy offered support. He had dealt with the same issue once. He mentioned Sylvester Bryant. My friend praised his expertise. I contacted him at once. His email is [email protected]. Sylvester Bryant changed everything. He heard my tale with no blame. His crew jumped in quickly. They checked all scam details first. One by one, they followed my lost USDT trail. They used software to track the blockchain. That is the open log of coin transfers. It reveals fund paths. Scammers try to cover their steps. Bryant's team went far. They reached out to related platforms and services. Each day brought progress. No easy ways. They shared updates with me always. Each message and talk stayed open and true. Finally, they got back every dollar. My $52,000 returned whole. The effort needed drive and resolve. Bryant's fairness shone through. He added no secret costs. Only fair pay for the job. My worry faded. I relaxed once more. Nights grew calm. My faith in recovery grew strong. If fraud stole your funds, move fast. Contact Sylvester Bryant. He treats such cases with skill.

I never imagined I’d fall for a crypto romance scam but it happened. Over the course of a few months, I sent nearly $184,000 worth of Bitcoin to someone I genuinely believed I was building a future with. When they disappeared without a trace, I was left heartbroken, humiliated, and financially devastated. For a long time, I didn’t tell anyone. I felt ashamed. But eventually, while searching for answers, I came across a Reddit thread that mentioned Agent Jasmine Lopez a crypto recovery agent. I reached out, not expecting much. To my surprise, she treated me with kindness, not judgment. She used advanced tools like blockchain forensics, IP tracing, and smart contract analysis and with persistence and legal support, she was able to recover nearly 85% of what I lost. I know not everyone gets that kind of outcome, but thanks to [email protected] WhatsApp at +44 736-644-5035, I’ve started to reclaim not just my assets, but my confidence and peace of mind. If you’re going through something similar, you’re not alone and there is hope.

i Lost $200,000 to a phishing scam in 2022. Funds went to a mixer service. Davies traced 70% through Ethereum layers. He teamed with an exchange to freeze the rest. i got $140,000 back in six months. Hiring Davies means clear steps. You share details. He checks facts. Then, the hunt begins. Expect ups and downs, but his plan keeps it steady. you can reach out to him by sending an email to anthonydaviestech {@} gmail com

Firstly, the importance of verifying the authenticity of online communications, especially those about financial matters. Secondly, the potential for recovery exists even in cases where it seems hopeless, thanks to innovative services like TechY Force Cyber Retrieval. Lastly, the cryptocurrency community needs to be more aware of these risks and the available solutions to combat them. My experience serves as a warning to others to be cautious of online impersonators and never to underestimate the potential for recovery in the face of theft. It also highlights the critical role that professional retrieval services can play in securing your digital assets. In conclusion, while the cryptocurrency space offers unparalleled opportunities, it also presents unique challenges, and being informed and vigilant is key to navigating this landscape safely.

Earlier this year, I made a mistake that changed everything. I downloaded what I thought was a legitimate trading app I’d found through a Telegram channel. At first, everything looked real until I tried to withdraw. My entire investment vanished into a bot account, and that’s when the truth hit me: I had been scammed. I can’t describe the feeling. It was as if the ground dropped out from under me. I blamed myself. I felt stupid, ashamed, helpless every painful emotion at once. For a while, I couldn’t even talk about it. I thought no one would understand. But then I got connected to the best female expert AGENT Jasmine Lopez,,( [email protected] ) ,She didn’t brush me off or judge me. She took my fear seriously. She followed leads I didn’t even know existed, and identified multiple off-chain indicators and wallet clusters linked to the scammer network, she helped me understand what had truly happened behind the scenes. For the first time since everything fell apart, I felt hope. Hearing that other people students, parents, hardworking people had been targeted the same way made me realize I wasn’t alone. What happened to us wasn’t stupidity. It was a coordinated attack. We were prey in a system built to deceive. And somehow, through all the chaos, Agent Jasmine stepped in and shined a light into the darkest moment of my life. I’m still healing from the experience. It changed me. But it also reminded me that even when you think you’re at the end, sometimes a lifeline appears where you least expect it. Contact her at [email protected] WhatsApp at +44 736-644-5035.

I’m June Watkins from California. I never thought I’d lose my life savings in Bitcoin. One wrong click, a fake wallet update, and $187,000 vanished in seconds. I cried for days, felt stupid, ashamed, and completely hopeless. But God wouldn’t let me stay silent or defeated. A friend sent me a simple message: “Contact Mbcoin Recovery Group, they specialize in this.” I was skeptical (there are so many scammers), but something in my spirit said “try.” I reached out to Mbcoin Recovery Group through their official site and within minutes their team responded with kindness and clarity. They walked with me step by step, and stayed in constant contact. Three days later, I watched in tears as every single Bitcoin returned to my wallet, 100% recovered. God turned my mess into a message and my shame into a testimony! If you’ve lost crypto and feel it’s gone forever, don’t give up. I’m living proof that recovery is possible. Thank you, Mbcoin Recovery Group, and thank You, Jesus, for never leaving me stranded. contact: (https://mbcoinrecoverygrou.wixsite.com/mb-coin-recovery) (Email: [email protected]) (Call Number: +1 346 954-1564)

My name is Elizabeth Madison currently living in New York. There was a time I felt completely broken. I had trusted a fraudulent bitcoin investment organization, who turned out to be a fraudster. I sent money, believing their sweet words and promises on the interest rate I will get back in return, only to realize later that I’ve been scammed. On the day of withdrawal there was no money in my account. The pain hit deep. I couldn’t sleep, I kept asking myself how I could have been so careless, meanwhile my mom was battling with a stroke and the expenses were too much. For days, I cried and blamed myself. The betrayal, the disappointment and my mom's health issues all of this stress made me want to give up on life. But one day, I decided that sitting in pain wouldn’t solve anything. I picked myself up and chose to fight for what I lost then I came across GREAT WHIP RECOVERY CYBER SERVICES and saw how he helped people recover their funds from online fraud. I emailed all the transactions and paperwork I had with the fraudulent organization and they helped me recover all my lost money in just five days.
